The design’s strength lies in its mechanical precision and robust internal structure, making it suitable for various industrial applications such as heat exchangers, process lines, and steam tracing systems.

Miyawaki SCCV System – Advanced Valve Performance

At the heart of the Miyawaki ES12N Inverted Bucket Steam Trap is Miyawaki’s proprietary SCCV (Self Closing and Centering Valve) System.This innovative mechanism ensures:

  • Superb valve sealing performance

  • Minimized mechanical wear due to moderated lever force

  • Consistent and accurate operation, even under fluctuating load conditions

The SCCV system allows the trap to maintain tight shutoff and stable function, extending its operational lifespan and reducing maintenance downtime.

Compact Power – The Advantage of the Miyawaki ES12N Inverted Bucket Steam Trap

As part of Miyawaki’s low-discharge ES Series, the Miyawaki ES12N Inverted Bucket Steam Trap combines compactness with precision. Its efficient mechanical design provides stable discharge capacity while maintaining a smaller footprint compared to conventional models—making it ideal for installations with limited space but high performance requirements.
